I'm currently thinking about buying a 27" iMac after my current Windows computer. I know Mac OS X is awesome, but I was wondering how is gaming on this OS. What I mean is, how much of the current game releases are both on Windows and Mac OS X ? And if they are not released on Mac OS X, is it possible (performance speaking) to play them on the Windows VM ?

I know my question might not be clear. If that is so, please comment, and tell me what I explained wrong, and I'll try to improve it.

I'm a big League Of Legends player, and I like other MMO from times to times. I have preordered Star Wars : The Old Republic too

Yeah indeed the Apple section on Steam is really limited, and there are few "popular" games. I'll check your link on boot camp

Boot Camp is great; I had a 20" iMac from the first release of the aluminum body style (late 2007 / early 2008?), so not an incredible powerhouse. Running Win XP under Boot Camp I played the likes of Oblivion and Bioshock (both new at the time) with graphics cranked up, both ran beautifully.
